Operating system command injection vulnerability in the SVN integration component of BugTracker.NET. The application incorporates the value of the field corresponding to the repository into an svn.exe command without properly validating it. An authenticated user with administrator privileges could store manipulated arguments in the database and subsequently cause them to be processed by the revision comparison functionality. A successful exploit could allow the execution of arbitrary commands with the privileges of the account used by the application. To exploit this vulnerability, svn.exe must be installed and capable of being invoked by the service.
